FOLDING SEAT AND BACK REST Filed Jan. 3l, 1933 2 Sheets-Sheet 2 l O Olll Il Ill ll rNvENTon MTTORNEY Patented Apr. 16, 1935 UNITED estarasinstru rarest oFFicE 2 Claims.

This invention relates to certain new and useful improvements in acombination knock-down seat and back rest.

Another of the objects of the invention consists 5 of mountings for theback upon the seat to facilitate folding the back with relation to theseat in such manner as to permit the device to be conveniently carriedunder the arm.

An additional object of the invention embodies the provision of alocking element upon the seat whereby the back may be retained againstdisplacement when swung to occupy either of its respective positions.

With the above and other objects in view, the invention furthei`consists of the following novel features and details of construction, tobe hereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings:-

Figure 1 is a side elevation of the present invention.

Figure 2 is a longitudinal sectional View taken through the device whenknocked down.

Figure 3 is a rear elevation of the invention.

Figure 4 is a sectional View taken on line 4 4 of Figure 3.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, ther reference characters il and I lindicate the side rails of my form of seat having notches i2 arrangedinthe upper edges thereof to accommodate cross rails It having the uppersurfaces thereof in alignment with that of the rails I@ and I I. SlatsIll are arranged at intervals upon the rails I3 in the manner suggestedinFigures 3 and 4 of the drawings, after `the manner of the usual lawnbench construction.

Extensions I5, carried by and upstanding from the rearrnost projectingends of the rails it and II, support therebetween a rod member Itpivotally supporting the side members il of the seat back. The sidemembers, aforementioned, carry transverse and longitudinal slats Itwhich may intersect for connection in any desired manner from thestandpoint of strength or ornamentation. A rod member til, carried byjournal members 2 I located upon the rearmost projecting edges of theside members il, project outwardly far enough to pierce appropriateportions oi the arm rests 22. As shown in Figure l of the drawings, thearm rests 22 are provided with legs 23 having hinge connections 2li attheir upper ends with the under sides of the arm rests. ties of the legsZ3, however, are inclined to bear The upper extremiflush against theunder sides of the arm rests 22 when same are shifted to occupy activepositions. A rod member 25, supported by the rails I and II, projectsoutwardly therebeyond to pivotally support the lowermost ends of the legmembers` 23 whereby the latter may be shifted to occupy positionssuggested by dotted lines in Figure 2 of the drawings when the seat isknocked down.

A spring actuated plunger pin 26, mounted in either or both of the railsIl) and II, is designed to be disposed in the path of movement of theshorter ends of the side members Il for the seat back whereby the latterwill be lockingly retained against accidental displacement when shiftedto occupy either of its extreme positions.

As suggested from the Figure 1 illustration, the device may be employedto useful eiTect upon concrete and other steps, upon the usual slabseats at amphitheaters and the like where the seats are usually hard anddo not afford such comforts as back and arm rests.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention, what claimed is:

1. A collapsible chair embodying side rails, for,- ward and rearwardcross rails connecting the side rails and slats terminally connected tosaid cross rails, extensions formed integral with the side rails and onthe rear end thereof and extending above the top edge of the rails, aback formed of side members, the lower ends of the side members engagingwith the confronting faces of said extensions, a transversely disposedrod passing through the side members of the back and said extensions forpivotally connecting the back with the extensions and permitting of thefolding of the back upon said slats, bearing members on the rear face ofthe side members, arm rests, a second transverse rod journalled in thebearings of the side members and loosely projecting through the rearends of the arm rests, legs hinged at the forward end of said arm rests,the opposite ends of the legs contacting with the outer face of the saidside rails, a transverse member passing through the lower ends of thelegs and side rails for pivotally connecting the legs to the side railsand in Contact with the outer faces thereof.

2. A collapsible chair embodying side rails, forward and rearward crossrails connecting the side rails and slats terminally connected to saidcross rails, extensions formed integral with the side rails and on therear end thereof and extending above the top edge of the rails, a backformed of side members, the lower ends of the side members engaging withthe confronting faces of said extensions, a transversely disposed rodpassing through the side members of the back and said extensions forpivotally connecting the back with the extensions and permitting of thefolding of the back upon said slats, bearing members on the rear face ofthe side members, arm rests, a second transverse rod journalled in thebearings of the side members and loosely projecting through the rearends of the arm rests, legs hinged at the forward end of said arm rests,the opposite ends of the legs contacting with the outer face of the siderails, a transverse member passing through the lower ends of the legsand side rails for pivotally connecting the legs to the side rails andin contact with the outer face thereof, a. spring pressed pin mounted inone of said extensions and alternately contacting with the front andrear faces of one of the side mem bers of the back for supporting thechair in a folded and unfolded position.
